MODEL WDW-300E 

COMPUTER CONTROLLED ELECTRONIC UNIVERSAL TESTING MACHINE

 

Main application:

 

    WDW-300E computer controlled electronic universal testing machine is mainly used for testing and analyzing the tensile, compression, bending, shearing, tearing, peeling and other mechanical properties of non-metallic materials, such as metal wire, rubber plastic, waterproof roll, wire and cable, chemical fiber textile, etc. according to GB, ISO, JIS, ASTM, DIN and various standards provided by users. It is an ideal testing equipment for scientific research institutes, colleges and universities, industrial and mining enterprises, technical supervision, commodity inspection and arbitration departments.

 

Main machine

 

  • The main machine adopts floor type frame structure with high strength, small deformation and beautiful appearance.

  • Imported high-precision ball screw is adopted, with efficient and stable transmission.

  • High precision spoke load sensor is adopted, with high measurement accuracy and good stability;

  • The transmission part adopts circular arc tooth synchronous belt transmission, and there is no gap in both directions during the transmission process.

  • AC servo motor and drive system are adopted to ensure stable transmission and torque, with overcurrent, overvoltage, overload and other protection devices, and the speed regulation ratio can be greater than 1:100000

  • Equipped with hydraulic clamping system.

  • The clamp is specially designed, with firm clamping, convenient operation and no jaw slip.

  • The special process ensures the coaxiality of the testing machine and eliminates the influence of irregular samples on the sensor.

 

Control system

 

    The full digital closed-loop measurement and control system has many advanced characteristics and technological innovations:

  • Four closed-loop controls of test force, sample deformation, beam displacement and test process are realized.

  • The data acquisition system consists of 4 high-precision 32-bit A / D conversion channels. The highest resolution is 1 / 300000, and the whole process is not divided.

  • Original famous brand integrated devices are selected, with full digital design.

  • Comply with PCI bus standard, microcomputer automatic identification and installation, and achieve "plug and test".

  • The electronic measuring system has no potentiometer and other analog components to ensure interchangeability and facilitate maintenance and replacement.
